ALETTE A Drop Seal Bar 1230 mm Scissor-Action 14 mm Max Drop with Support Bracket

Product Overview

The ALETTE A Drop Seal Bar 1230 mm with support is used on the bottom edge of doors to create an adjustable seal between the threshold and the door leaf. It is commonly installed in commercial and residential door assemblies where sealing, acoustic, or energy efficiency is required. The device automatically engages with the floor surface, retracting when the door is opened so the seal does not drag on carpets or flooring.

A key distinguishing feature of this model is its maximum scissor-action seal drop of up to 14 mm, providing reliable sealing even on floors with significant unevenness. This ensures project compliance with air draft and sound insulation requirements, minimizing risk of failed acceptance on demanding builds. The ALETTE A is especially suited for large commercial doors or renovations where thresholds vary and precise adaptation is necessary.
